Without further discussion we assume that before hadronization in the QGP epoch of temperature \(T>150\)  MeV the strangeness formation processes studied in laboratory [1]} are fast enough to assure chemical equilibrium - hence the Universe undergoing a relatively slow on hadronic time scale phase transformation emerges from QGP near to chemical equilibrium abundance. In this transition the excess QGP entropy as compared to HG is absorbed in additional Universe comoving volume expansion while excess strangeness has time to reequilibrate into equilibrium HG abundance.
